With TCM v3.2, the two major SPC-4 SCSI target mode fabric features that have now been completed: Persistent Reservation APTPL and implict/explict ALUA are the first all optional SPC4 defined feature implementation of PR and ALUA in the Linux OSS target theatre using an upstream user-driven virtual filesystem directory hierarchy structure based on configfs that can be configured in realtime in combination with interpreted userspace code. Both of these new features are now being used to provide Persistent Reservations across target power loss and asymmetric multipath I/O to both Linux and non-Linux clients. There is also an optional ALUA transition delay logic that has been included to futher debug and improve existing upstream client side Linux kernel code using TCM v3.2. These patches have been diffed against v2.6.31, and tested on x86 32-bit HVM, x86_64 KVM, and powerpc. There is cleanup work continuing to make the TCM code to use dprintk(), and some include cleanups, and other minor fixes. The code has also been run through checkpatch again since the posting in April, and all errors have been removed, with the exception of one ConfigFS macro define triggering a checkpatch false positive. As with the posting of the TCM v3.0 code earlier in April, I have decided to break up the submissions into the generic target_core_mod piece (this patch series) and then a seperate one that will be appearing in the next days for v3.2 of the LIO-Target iSCSI fabric module.
